在啤酒的世界里，每一口清爽醇厚的口感背后，都有一位默默工作的无名英雄——啤酒冷藏机。虽然它不像啤酒本身那样直接呈现给消费者，但它在啤酒的生产、储存和供应中起着至关重要的作用。
啤酒冷水机的核心工作原理是基于热力学中的制冷循环和热交换原理。它主要由压缩机、冷凝器、膨胀阀、蒸发器等关键部件组成。首先，压缩机压缩制冷剂气体，提高其温度和压力。高温高压的制冷剂气体进入冷凝器，与外界空气或水进行热交换散热，制冷剂气体冷凝成液体。液态制冷剂经膨胀阀减压后进入蒸发器。在蒸发器中，制冷剂迅速蒸发并吸收大量的热量，而这些热量恰恰来自于需要冷却的啤酒。这样，啤酒中的热量就传递给制冷剂，从而实现啤酒的冷却。
To cool beer more efficiently, a coolant such as ethylene glycol is usually used as an intermediate medium. Ethylene glycol flows in the circulation system of the chiller. It is first cooled in the evaporator and then transported to the heat exchanger in contact with beer. Beer flows in the pipeline of the heat exchanger and exchanges heat with ethylene glycol, thereby rapidly reducing temperature. This indirect cooling method can not only precisely control the cooling temperature of beer but also avoid the pollution problem that may be caused by direct contact between the refrigerant and beer.
In every link of beer brewing, temperature control is crucial. From malt crushing, saccharification to fermentation, each step needs to be carried out within a specific temperature range to ensure the activity of yeast and the formation of beer flavor. The beer chiller in this process is like an accurate “temperature regulator”。例如，在糖化阶段，需要将麦芽和水的混合物加热到一定温度，然后通过冷水机冷却到适合酶作用的温度，以促进淀粉转化为糖。在发酵阶段，更需要温度控制，以保证酵母的正常发酵和啤酒风味的稳定。啤酒冷水机可以为发酵罐提供稳定的低温环境，使酵母能够在最佳状态下工作，产生丰富的风味物质和二氧化碳。
啤酒储存过程中，温度波动会对其品质产生很大影响。过高的温度会加速啤酒的变质，使其失去原有的风味和口感。甚至可能导致啤酒变得混浊或产生异常气味。啤酒冷水机为啤酒储存提供了可靠的保证。通过保持储存环境温度较低且恒定，有效延长啤酒的保质期和保鲜期。无论是在大型啤酒仓库还是小型酒吧酒窖，啤酒冷水机都能确保啤酒在储存过程中始终保持良好的品质。
在酒吧、餐厅等场所，为顾客提供口感清凉、泡沫丰富的啤酒至关重要。啤酒冷水机在啤酒供应环节中发挥着关键作用。它可以将啤酒从储存温度快速冷却到适合饮用的温度，确保每一杯啤酒在交付给顾客时都能达到最佳的口感状态。同时，啤酒输送管道中循环的冷水还可以防止管道内啤酒因温度升高而产生过多泡沫或变质，保证啤酒供应的稳定性和连续性。
啤酒冷水机采用先进的温控系统，能精确地将啤酒冷却到所需温度，误差范围极小。这种精确的温度控制对于确保啤酒的质量和口味一致性至关重要。无论是大规模的啤酒生产，还是小规模的酒吧经营，通过啤酒冷水机都可以获得稳定的低温环境，保证每批啤酒都具有同样的高品质。
随着能源成本的不断上升，节能成为啤酒行业关注的焦点。现代啤酒冷水机采用高效制冷技术和节能设计，在保证冷却效果的同时，可以最大限度地降低能耗。例如，一些先进的冷水机采用变频压缩机技术，可以根据实际制冷需求自动调节压缩机的运行频率，从而避免能源浪费。此外，良好的保温设计和优化的管道布局也有助于减少能源损失，提高能源利用效率。
在啤酒生产和销售过程中，任何设备故障都可能导致生产中断或服务质量下降，给企业造成损失。啤酒冷水机通常具有较高的可靠性和稳定性。他们采用优质的零部件和先进的制造工艺，确保设备能够长期稳定运行。同时，很多啤酒冷水机还配备了完善的故障诊断和保护系统，可以及时发现并解决潜在问题，保证设备的安全运行。
不同规模的啤酒企业和场所对啤酒冷水机的需求不同。为了满足这种多样化的需求，啤酒冷水机具有很强的灵活性和可扩展性。可以根据实际生产或销售规模进行定制，范围从小型台式冷水机到大型工业级冷水机。而且，对于一些企业来说，如果未来业务发展需要增加啤酒产量或扩大销售范围，现有的啤酒冷水机系统也可以相对容易地进行扩展和升级，以满足新的需求。
随着技术的不断进步和啤酒行业的不断发展，啤酒冷水机也在不断创新和发展。未来，啤酒冷水机将朝着更加智能、环保、高效的方向发展。
智能化将成为啤酒冷水机发展的重要趋势之一。通过集成先进的传感器、控制器和通信技术，啤酒冷水机将能够实现远程监控、自动调节和智能诊断等功能。操作人员可以通过手机或电脑随时随地监控冷水机的运行状态，调整温度参数，及时获取设备的故障预警信息。这种智能控制方法不仅提高了设备的管理效率，而且进一步优化了啤酒冷却过程，保证了啤酒品质的稳定性。
As global attention to environmental protection is increasing, the beer chiller industry is also actively seeking more environmentally friendly refrigerant solutions. Traditional refrigerants such as Freon, although having good refrigeration performance, have a destructive effect on the ozone layer and will produce greenhouse gas emissions. Therefore, in the future, beer chillers will increasingly adopt environmentally friendly refrigerants such as natural refrigerants (such as carbon dioxide, ammonia, etc.) or new synthetic refrigerants. These environmentally friendly refrigerants can not only meet the refrigeration needs but also have a lower environmental impact and meet the requirements of sustainable development.
为了进一步降低能耗，啤酒冷水机制造商将不断研究和应用新型高效节能技术。例如，热回收技术可以回收冷水机组在制冷过程中产生的废热，用于加热水或其他需要热能的环节，从而提高能源的综合利用效率。此外，新型制冷循环系统和高效压缩机技术也将不断涌现，进一步提高啤酒冷水机的能效比，为啤酒企业带来更大的经济效益和环境效益。
啤酒冷水机作为啤酒行业不可或缺的设备，对于保证啤酒质量、提高生产效率、满足消费者需求发挥着重要作用。随着技术的不断进步和创新，啤酒冷水机也将不断发展和完善，为啤酒行业未来的发展提供更加坚实的支撑。无论是炎热的夏天还是寒冷的冬天，它都会不断地默默地为我们带来那杯清凉的啤酒，让我们充分享受啤酒带来的美好时光。

为了防止这些问题，适当的冷水机的设计成为成功的 DWC 系统的关键方面。
制冷量: Determine the cooling capacity required for your system. This is typically measured in BTUs (British Thermal Units). Factors influencing this calculation include:
A simple way to estimate the cooling load is to use the formula:
Cooling Load (BTU/hr)=Volume of Water (gallons)×Temperature Drop (°F)×8.34
Here, the factor 8.34 reflects the weight of one gallon of water.
一旦您的冷水机投入运行，定期维护将确保其使用寿命和效率：
Designing an effective water chiller for your hydroponic DWC system involves thorough planning and understanding of both the science behind plant physiology and the practicalities of thermal management. By carefully calculating your needs, selecting the right components, and implementing a reliable control system, you will enhance the conditions for your plants to thrive.

在工业制造领域，特别是在需要应用保护涂层的领域，热喷涂技术的实施已成为一项关键的创新。通过使用冷水机，这些过程的有效性和效率得到显着提高，冷水机在热喷雾冷却中发挥着不可或缺的作用。本文旨在探讨热喷涂工艺背后的机制、冷水机在这些应用中的重要性，以及先进冷却解决方案对表面涂层质量和寿命的影响。
Thermal spray technology encompasses a variety of techniques that involve the deposition of materials onto a substrate to create a coating. This method is typically employed to enhance the wear resistance, thermal barrier properties, and corrosion resistance of components in a wide range of industries, including aerospace, automotive, and manufacturing. The process involves melting or softening a material—usually in the form of powders or wires—which is then propelled onto a substrate. The cooling of the waxed surface post-deposition crucially affects the characteristics of the final coating, influencing its microstructure and performance attributes.
热喷涂涂层的质量取决于多种因素，包括基材温度、颗粒速度，以及重要的是应用后的冷却速率。快速冷却可以形成精细的微观结构，最大限度地减少孔隙率等缺陷并提高对基材的附着力。因此，有效的冷却解决方案在该领域备受青睐。
冷水机是控制热喷涂部件温度环境的一种手段。通过调节冷却参数，这些系统可确保涂层获得所需的性能，而不会影响材料的完整性。冷却水系统有效吸收喷涂过程中产生的多余热量，从而迅速降低温度并促进沉积材料发生有利的相变。
冷水机的部署具有几个明显的优势。其中最重要的是保持最佳工作温度的能力，这对于实现所需的微观结构至关重要。使用冷冻水实现的快速冷却速率可以促进快速凝固，有助于形成致密、细晶粒的微观结构，这些结构通常与增强的机械性能相关。
此外，冷水机在运行一致性方面提供的控制能力怎么强调也不为过。保持均匀的冷却温度有助于降低因温度梯度不均匀而引起的热变形或开裂的风险。这对于对其零部件要求高精度和可靠性的行业尤其重要。此外，将冷水机集成到热喷涂系统中可以实现连续运行，减少停机时间并提高生产率。
随着工业需求的发展，与热喷涂应用中的冷却相关的技术也在不断发展。现代冷水机系统通常配备先进的控制系统，可以根据热喷涂过程的反馈实时监控和调整温度。这些技术进步使操作员能够对偏离最佳条件的情况做出快速反应，确保每次都能获得高质量的涂层。
此外，能源效率已成为当代制冷系统的一个重要考虑因素。随着能源成本的上升和对可持续性的日益关注，利用环保制冷剂和节能运行模式的创新设计变得越来越普遍。这些进步不仅使制造商受益于成本节约，而且还为环境管理做出了积极贡献。
展望未来，热喷雾冷却冷水机的未来似乎有望取得重大进步。物联网集成等新兴技术（其中冷却器可以与热喷涂设备实时通信）可以为进一步提高涂层质量和运营效率的新颖应用铺平道路。同样，将传统水冷却与其他方法（例如空气冷却或相变材料）相结合的混合冷却系统的开发为在热喷涂应用中实现最佳热管理提供了令人兴奋的可能性。
冷水机是热喷涂冷却领域的重要组成部分，显着影响制造中应用的涂层的质量和耐用性。随着行业的发展和对更高效、更可靠流程的需求，先进冷却技术的集成确实将在实现更高的性能标准方面发挥关键作用。围绕冷却解决方案正在进行的研究和创新为热喷涂技术带来了光明的未来，确保其作为现代制造实践中不可或缺的工具的突出地位。
热喷涂技术通过将熔融或半熔融材料应用于基材以改善表面性能，在先进制造和表面工程中发挥着至关重要的作用。这些技术对于包括航空航天和汽车在内的各个行业都至关重要。热喷涂的有效性取决于多个参数，其中温度调节是最关键的。冷水机对于热喷雾冷却过程至关重要，可提高运行效率。本文探讨了冷水机在热喷雾冷却中的重要性，包括其原理、类型、优点以及对运行效率的影响。
热喷涂涉及将材料沉积到基材上形成涂层，该涂层可以增强耐磨性、耐腐蚀性和隔热性等性能。热喷涂过程通常会产生大量热量，这会对工件和所用设备的性能产生不利影响。因此，有效的冷却系统对于减轻热量积聚、防止热变形并保持所处理基材的完整性至关重要。冷水机通过使冷冻水循环通过喷涂设备周围的盘管或夹套来促进这种冷却，吸收热喷涂过程中产生的多余热量。
冷水机根据热交换和热力学的基本原理运行。冷水机的主要功能是利用制冷循环去除流体中的热量。工业环境中使用的两种主要类型的冷水机是风冷式冷水机和水冷式冷水机。
这些装置利用环境空气来冷却制冷剂盘管。当制冷剂从循环水中吸收热量后蒸发时，它被压缩机压缩，穿过冷凝器，将热量释放到大气中。然后冷冻水循环到热喷涂设备中，确保部件保持在最佳温度。
这些系统使用冷却塔来散热。制冷剂过程保持相似，但水不依赖空气，而是通过冷却塔循环，在冷却塔中吸收冷凝器的热量。水冷式冷水机在需要高冷却负载的应用中往往效率更高，并且可以处理更大容量的冷冻水，这使得它们特别适合广泛的热喷涂操作。
将冷水机纳入热喷涂工艺可带来诸多好处，增强了其在现代制造实践中的必要性。
While the advantages of water chillers in thermal spray cooling are substantial, there are also challenges to consider. The initial investment and maintenance costs of water chillers can be significant, especially for small or medium-sized enterprises. Additionally, the operation of chillers can demand a consistent energy supply, which can be a point of contention in regions where energy access is limited or unstable.
此外，安装和集成到现有系统的复杂性需要大量的规划和专业知识。必须建立适当的维护实践以确保冷水机组的使用寿命，包括定期检查、清洁和流体管理。如果不能充分维护这些系统，可能会抵消它们提供的许多好处。
总之，冷水机是热喷涂冷却过程中不可或缺的组成部分，可提高涂层质量、延长设备寿命并提高运行效率。尽管必须谨慎应对成本和维护等挑战，但冷水机在维持热控制方面所带来的好处凸显了它们在先进制造实践中的关键作用。随着行业的不断发展，对高效温度调节的需求仍然不可或缺，这确保冷水机将在热喷涂技术的未来格局中发挥重要作用。
How to choose the right type of heat exchanger for your application？It always be a big problem for anybody who don’t understand the theory of heat exchangers.
So, before you make the decision, you should find out this question :
As its name suggests, a heat exchanger is a tool that enables efficient temperature exchange between two materials , which are at different temperatures , within the heat exchanger. One side is called a heat source and the other is called a cold source.
The exchange of temperature between different substances requires different types of heat exchangers.
On the market , common types of heat exchanger are Shell-and-tube heat exchanger, heat exchanger with tank, immersed heat exchanger, box heat exchanger, plate heat exchanger. Shell-and-tube heat exchanger according to the arrangement of its tubes, can be divided into: coil heat exchanger, tube-in-line heat exchanger。
But under what conditions and what types of heat exchangers are suitable What factors should be considered in the selection of heat exchangers Let’s take a look at the scenarios we don’t use.
fish are very sensitive to changes in water environment, especially water cleanliness and water temperature. In particular, the use of chillers/thermostats to control water temperature is very necessary for the cultivation of seafood and fish. For the small seafood pool thermostat, we generally choose titanium coil shell-and-tube heat exchanger, or directly use titanium immersion tube heat exchanger. Titanium has a good corrosion resistance, so in the sea water treatment applications are quite outstanding, but also very common, the normal service life of up to 5 years. If the use of copper or stainless steel pipe made of heat exchanger, its life will be greatly reduced. Because its function is mainly used for refrigeration, we often call this kind of titanium heat exchanger titanium evaporator.
industrial production, for the maintenance of equipment, life, and process requirements, often need to use the water chiller. Such as laser equipment, laser equipment in the course of operation, laser generator such as diode, will continue to produce high heat. If the equipment overheats for a long time, this will damage the life of the laser generator. Therefore, the laser equipment must be equipped with a corresponding refrigeration capacity of the chiller. In the laser water chiller, generally use small volume of stainless steel coil shell-and-tube heat exchanger or stainless steel heat exchanger tank.
In addition to laser equipment, injection molding machine, extruder and other plastic processing equipment also need to be equipped with temperature controller. The chillers for this type of equipment are generally copper-tube stainless steel tank-type evaporators. Generally speaking, the chillers of this type of equipment need not high refrigerating capacity and the required refrigerating temperature is not low, so they are usually air-cooled chillers with built-in coil box or shell-and-tube evaporator.
The requirements of these applications for heat exchangers are high, both in terms of heat transfer efficiency and shock resistance. Therefore this kind of chiller generally uses the coaxial sleeve type heat exchanger, the row tube type heat exchanger or the plate type heat exchanger. These two types of heat exchangers have small internal volume, high heat transfer efficiency and strong external structure, and are very suitable for high-power refrigeration equipment. In particular, open, screw-type chillers.
And this kind of chiller is water-cooled chiller generally. After all, air-cooled chillers are difficult to achieve a high heat transfer ratio, and water-cooled heat exchangers in the heat transfer ratio has an absolute advantage. However, water-cooled chillers need to use cold water tower, the cold water tower is huge, so the heat transfer ratio requirements are not so high chiller equipment, the general recommendation is air-cooled chillers.

In the production work of various industries, the commonly used chillers are air-cooled chillers or water-cooled chillers. These two types of chillers are the most common in the market.
Air-cooled and water-cooled industrial-grade chillers are critical for industrial processes, such as plastics, pharmaceuticals, commercial printing, and transportation manufacturing. Our clients also rely on them for brewing processes, dairy farm operations, and medical equipment processing.
Both air-cooled and water-cooled chillers work by removing the heat from your processes so that your equipment stays cool, so they can keep running strong. In this post, we’re providing an insider look at the main components of a process chiller and the importance of each one.
If you’ve ever wondered what’s inside a chiller, here are the four main components of both air-cooled and water-cooled process chillers to know about the 4main components of chillers and basic working principles of a water chiller.
The main engine of chiller cold compressor is screw and centrifugal compressor, and the commercial engine is scroll compressor.
In the refrigeration industry, common compressors can be divided into the following categories.
Rotor compressor is a positive-displacement rotary gas compressor. The compression volume is defined by the trochoidally rotating rotor mounted on an eccentric drive shaft with a typical 80 to 85% adiabatic efficiency.
Piston Compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure.
Screw compressor is a type of gas compressor, such as an air compressor, that uses a rotary-type positive-displacement mechanism. These compressors are common in industrial applications and replace more traditional piston compressors where larger volumes of compressed gas are needed, e.g. for large refrigeration cycles such as chillers, or for compressed air systems to operate air-driven tools such as jackhammers and impact wrenches.
Magnetic suspension centrifugal compressor is discharged from the air conditioner compressor through high temperature and high pressure freon, enters the condenser, releases heat to the copper tube cooling water, condenses into medium temperature and high pressure Freon liquid, and then depressurizes to low temperature and low pressure liquid through the shut-off valve, enters the evaporator, absorbs heat from the frozen water flowing through the copper tube in the evaporator shell, gasifies into low temperature and low pressure gas, and then inhales into the compressor, which is used in the compressor Through this cycle, the purpose of cooling is achieved.
Evaporator of industrial chiller
Ordinary, there are 3 kinds of Evaporator we would use: Dry Evaporator / Full liquid Evaporator / Fall Film Evaporator
The working principle is the refrigerant flows in the tube and the water flows outside the tube cluster. Generally, the problem of oil accumulation does not exist when the lubricating oil from the shell enters the compressor with the refrigerant.
The dry evaporator is mainly composed of heat transfer tube, stripper, water discharge tube, refrigerant inlet tube, refrigerant outlet tube, refrigerant water inlet tube, refrigerant water outlet tube, left and right end caps and shell.
1.The heat transfer coefficient is high and the temperature difference is small;
2.The amount of refrigerant filled is less, generally only about 1 / 3 of that of full liquid type;
3.When the temperature is near 0 ℃, the water will not freeze, the heat transfer coefficient is 4.low and the temperature difference at the end is large;
5.Scale is easy to pay on the surface of evaporator copper tube, and is not easy to clean;
The refrigerant flows outside the pipe and the water flows inside the pipe. It is composed of shell, evaporation tube (high efficiency tube), tube sheet, support plate, etc.
1.The heat transfer coefficient is high and the temperature difference is small;
2.The water goes through the pipe and is easy to clean;
3.The refrigerant liquid basically fills the tube bundle, and the charge quantity is large;
4.The return oil of full liquid evaporator is difficult and unstable;
5.When the evaporation temperature of refrigeration system is lower than 0 ℃;
6.The water in the tube is easy to freeze and destroy the evaporation tube;
7.The static liquid column of the liquid in the full liquid evaporator increases the saturated evaporation temperature at the bottom.
The refrigerant is evenly separated from the distributor, forms a liquid film on the surface of the heat exchange tube, absorbs the heat in the tube and evaporates, and water flows in the tube, which is composed of distributor, shell, evaporation tube (high efficiency tube), tube sheet, support plate, etc.
1.High heat transfer coefficient and small end temperature difference (better than full liquid, better than dry type);
2.The lubricating oil accumulates at the bottom of the container and is easy to return due to its high concentration;
3.Avoid the liquid column in the full liquid evaporator to increase the saturated evaporation temperature at the bottom;
4.The main pipe phenomenon of falling film is avoided, the heat transfer is more uniform and the efficiency is higher;
5.The water goes through the pipe and is easy to clean;
6.When the evaporation temperature of refrigeration system is lower than 0 ℃, the water in the tube is easy to freeze and destroy the evaporation tube.
它是制冷系统的一部分，属于热交换器的一种，可以将气体或蒸汽转化为液体，并将管道中的热量以非常快的方式传递给管道附近的空气。冷凝器是一种放热装置，它将蒸发器吸收的热量与压缩机做功转换的热量一起传递给冷却介质。冷凝器的工作过程是一个放热过程，因此冷凝器的温度较高。
它由内置分离器、壳体、蒸发管（高效管）、管板、支撑板、过冷器等组成。
According to the different cooling medium, condensers can be divided into three types: water cooling type, air cooling type and evaporation type.
Water cooled condenser takes water as cooling medium and takes away condensation heat by the temperature rise of water. The cooling water is generally recycled, but the cooling tower or cool pool should be set in the system. According to its structure, water-cooled condenser can be divided into shell and tube condenser and tube and tube condenser.
The main features are as follows:
1) Because of the large cooling flow and high flow rate, the heat transfer coefficient is high.
2) Vertical installation covers a small area and can be installed outdoors.
3) The cooling water flows directly and the flow rate is large, so the requirement of water quality is not high. Generally, the common water can be used as cooling water.
4) The scale in the pipe is easy to clean, and it is not necessary to stop the refrigeration system.
5) The temperature rise of the cooling water in the vertical condenser is generally only 2-4 ℃, and the logarithmic average temperature difference is generally about 5-6 ℃, so the water consumption is large. And because the equipment is placed in the air, the pipe is easy to be corroded, and the leakage is easy to be found.
It has the similar shell structure with the vertical condenser, the main difference lies in the horizontal placement of the shell and the multi-channel flow of water.
Horizontal condenser is widely used in refrigeration system and freon refrigeration system, but its structure is slightly different. According to the horizontal condenser, the cooling tube is smooth seamless tube, while the cooling tube of Freon horizontal condenser is generally low rib copper tube.
This is due to the low exothermic coefficient of Freon. It is worth noting that some freon refrigeration units generally do not have liquid storage tanks. But only use a few rows of tubes at the bottom of the condenser, which is also used as a liquid storage tank.
制冷剂的蒸气从上方进入内管和外管之间的腔体，在内管的外表面上凝结，液体依次在外管底部向下流动，从下端流入储液器。
冷却水从冷凝器下部进入，依次经各排内管从冷凝器上部流出。这种冷凝器由于单管冷凝，介质流向相反，因此结构简单，易于制造，传热效果好。
Its disadvantage is that the metal consumption is large, and when the number of longitudinal tubes is large, the lower tube is filled with more liquid, so that the heat transfer area can not be fully utilized.
In addition, the compactness is poor, the cleaning is difficult, and a large number of connecting elbows are needed. Therefore, this kind of condenser has been rarely used in refrigeration device. Casing condenser is still widely used in small Freon air conditioning units.
Air cooled condenser takes air as cooling medium and takes away condensation heat by air temperature rise. This kind of condenser is suitable for the situation of extreme lack of water or water supply, and is commonly used in small freon refrigeration units. According to the different ways of air flow, it can be divided into natural convection and forced convection.
The heat transfer of evaporative condenser mainly depends on the evaporation of cooling water in the air to absorb the latent heat of gasification. According to the way of air flow, it can be divided into suction type and pressure type.
蒸发式冷凝器由冷却管组、供水设备、风机、挡水板、箱体等组成。冷却管组是由无缝管弯制而成的蛇形盘管组，安装在薄钢板制成的长方形箱体内。箱体两侧或顶部设有通风机，箱体底部还用作冷却水循环水池。

冷水机节流装置
主要作用是节流减压、控制和调节制冷剂流量和过热度。
Double orifice plate: slow adjustment response; almost no adjustment ability; small energy adjustment range; low cost.
Electronic expansion valve: simple structure, small resistance, wide energy regulation, rapid response to energy efficiency regulation, high cost.
Pro tip: For low-temperature requirements, ask about electronic expansion valves (EEVs) to give you tight superheat control. They work by using a stepper motor that precisely regulates the valve’s position.

The 4 Main Components of Water Chillers 2021 阅读更多 ”
Before injection, the mold should be heated to a certain temperature. Then the plastic is not easy to solidify when it is integrated into the mold cavity in the injection molding process.
The problems like insufficient physical strength, delamination, incomplete injection and blocked flow channel are all related to the weakness of warm mold, which is the significance of warm mold.
During injection molding, the mold needs to be cooled after the whole cavity is filled with plastic. The plastic in molten state is rapidly cooled and solidified.
This is the normal definition of plastic molding chilling. But few people know the effect of cooling rate on the physical strength and internal stress of the final product.
In principle, for different injection parts, the injection mold can be cooled via a water chiller in the fastest way. The injection molding machine produced under this way will reach the best state in terms of physical strength and internal stress.
如果冷却时间过长，注塑件的物理强度会减弱，内应力会增加。会导致产品变形。最常见的问题是汽车仪表板等厚度薄、尺寸大的注塑件，这会给汽车制造商带来很大的麻烦。
每台注塑机设定相同数量的原材料。但当产品设计要求不同时，模具温度控制要求也不同。有些特殊产品对内应力和物理强度有很大的要求。不同的模具截面需要不同的温度曲线，这就需要多个模具温度控制器和注塑冷水机。

In the process of laser equipment running for a long time, the laser generator will generate high temperature continuously. If the temperature is too high, it will affect the normal operation of the laser generator, which is easy to be damaged.
In order to prolong the service life of the laser, it is necessary to cool the laser exciter by water circulation to ensure its normal operation under constant temperature or set temperature.
The water cooler is mainly used to cool the laser generator of the laser equipment, and control the temperature of the laser generator, so that the laser generator can work normally for a long time. Water chiller is a kind of water cooling equipment, which can provide constant temperature, constant current and constant pressure. The principle of the water chiller is to inject a certain amount of water into the internal water tank of the machine, cool the water through the refrigeration system of the water chiller, and then the water pump inside the machine will inject the low-temperature frozen water into the equipment to be cooled. The frozen water will take away the heat inside the machine, and return the high-temperature hot water to the water tank again for cooling, so as to achieve the purpose of cooling the equipment Use.
